Multi Stage Snowbound b2

So this is my first proper try at making a 3-stage A/D control point map. I originally came up with the idea of a snow-themed base right at the beginning of January 2012 and have been building and doing basic testing with bots (ie. route lengths and attack directions). Right now I'm at the stage of being able to release an alpha to be tested, in regards to whether the layout works, the arenas are the right size, the gameplay is balanced, etc., and really to ensure that it's fun to play before I start solidifying things and texturing/detailing/lighting.
